Concept and Demonstration of Individual Probe Actuation in Two-Dimensional Parallel Atomic Force Microscope System

Nico de Rooij, Hans Peter Herzig, Terunobu Akiyama, Peter Vettiger, Laure Aeschimann, André Meister

A concept of an array actuator that is used to control the tip-sample separation of cantilevers in a two-dimensional (2D) probe array scanning system is proposed in this article. The feasibility of the concept is demonstrated with a 10 × 10 array actuator ...

Near-field characterization of propagating optical modes in photonic crystal waveguides

Hans Peter Herzig

We analyze the propagating optical modes in a Silicon membrane photonic crystal waveguide, based on subwavelength-resolution amplitude and phase measurements of the optical fields using a heterodyne near-field scanning optical microscope (H-NSOM). Fourier ...

Tuning the resonance of a photonic crystal microcavity with an AFM probe

Hans Peter Herzig, Iwan Märki

We present theoretical and experimental results on switching and tuning of a two-dimensional photonic crystal resonant microcavity by means of a silicon AFM tip, probing the highly localized optical field in the vicinity of the cavity. On-off switching and ...

High Resolution Interference Microscopy: A Tool for Probing Optical Waves in the Far-Field on a Nanometric Length Scale

Hans Peter Herzig, René Dändliker, Toralf Scharf, Iwan Märki

High Resolution Interference Microscopy (HRIM) is a technique that allows the characterization of amplitude and phase of electromagnetic wave-fields in the far-field with a spatial accuracy that corresponds to a few nanometers in the object plane. Emphasis ...

Tunable microcavities in planar photonic crystals

Hans Peter Herzig, Iwan Märki

Micro- and nano-optical structures offer the possibility to control light on a wavelength scale. This allows further miniaturization of integrated optical circuits. Planar photonic crystal waveguides and microcavities are considered basic building blocks f ...

Optically tunable microcavity in a planar photonic crystal silicon waveguide buried in oxide

Hans Peter Herzig

We present all-optical tuning and switching of a microcavity inside a two-dimensional photonic crystal waveguide. The photonic crystal structure is fabricated in silicon-on-insulator using complementary metal-oxide semiconductor processing techniques based ...

Analysis of mode coupling due to spherical defects in ideal fully metal-coated scanning near-field optical microscopy probes

Hans Peter Herzig

We investigate the effect of defects in the metal-coating layer of a scanning near-field optical microscopy (SNOM) probe on the coupling of polarization modes using rigorous electromagnetic modeling tools. Because of practical limitations, we study an ense ...

Comparing glass and plastic refractive microlenses fabricated with different technologies

Hans Peter Herzig

We review the most important fabrication techniques for glass and plastic refractive microlenses and we quantitatively characterize in a systematic way the corresponding state-of-the-art microlenses, which we obtained from selected research groups. For all ...

On the chromatic aberration of microlenses

Hans Peter Herzig, Toralf Scharf

The optical properties of plano-convex refractive microlenses with low Fresnel Number (typically FN < 10) are investigated. It turns out that diffraction effects at the lens aperture limit the range of the effective focal length. The upper limit of the foc ...

Characterization of buried photonic crystal waveguides and microcavities fabricated by deep UV-lithography

Hans Peter Herzig, Ross Stanley, Iwan Märki

We present results of the optical characterization of silicon photonic crystal waveguides and microcavities that are completely buried in a silicon dioxide cladding and are fabricated by deep ultraviolet (UV) lithography. The advantages of buried waveguide ...
